This configuration is allowed by HP and supported by Oracle.
ASM over raw

A.11.18
Contact Oracle for ASM mirroring configuration requirements,
distance limitations and number of nodes supported. If you
are using ASM mirroring, use 11gR1 rather than 10gR2
because ASM on 11gR1 has features that enhance/improve
data replication across sites.
